Asco 300 Series 600 Amp Automatic Transfer Switch - 2 Pole

Asco 300 Series 600 Amp Automatic Transfer Switch - 2 Pole

True double-throw operation: The single solenoid design is inherently inter locked and prevents contacts from stopping between sources or from being in contact with both sources at the same time. There's no danger of the Series 300 ATS transferring loads to a dead source because the unique ASCO single-solenoid operator derives power to operate from the source to which the load is being transferred. Easy-to-read flush-mounted control and display panel provides LED indicators for switch position and source availability. It also includes test and time-delay bypass switches as standard features. Standard engine exerciser for weekly automatic testing of engine generator set with or without load. Adjustable time-delay feature prevents switch from being activated due to momentary utility power outages and generator dips.

Thompson Technology TS 870 Series Bypass / Isolation Automatic Transfer Switch

Thompson Technology TS 870 Series Bypass / Isolation Automatic Transfer Switch

The TS 870 bypass isolation switch provides the same reliable features that are available in the TS 870 automatic transfer switch.The TS 870 bypass isolation switch incorporates two basic types for bypass-isolation. Type "B" (double-sided ) isolates the transfer switch and can bypass either the utility or generator source of the load, as selected by the operator. Single-sided bypass types "D" (utility bypass) and "C" (generator bypass) can bypass only one source to the load (in accordance with CSA 282-00 - Institutional & Residential Buildings Occupancy Group Band C). Note: CSA 282-00 requires (as a minimum) a single sided bypass on the generator supply. The TS 870 series mechanisms utilize enclosed contact power switching units which provide a 100% continuous rating. The switches are mounted independently on a common frame.
